Description

Technical Field

[0001] The utility model relates to the technical field of paste reaction equipment, in particular to a vacuum distillation device of a paste reaction kettle. Background Art

[0002] In the synthesis process of printing synthetic paste, in order to ensure the smooth progress of polymerization during the product synthesis process, a mixed oil phase system is used to promote the heat dissipation effect of the reverse phase polymerization reaction process by enhancing the oil phase ratio. However, in the later stage of the reaction, it is necessary to distill out the excess low-boiling point water and oil through reduced pressure distillation, and recover the oil phase through the natural separation of oil and water to complete the synthesis concentration process. This process not only ensures the smooth progress of the product reaction, but also greatly reduces the proportion of the oil phase in the printing process. In addition, by adding a certain proportion of specific emulsifiers in the later stage of distillation and concentration, the flocculation effect of the oil phase system on the disperse dye can be further reduced, thereby improving the dispersibility of the dye.

[0003] However, in the current vacuum distillation process, increasing the temperature is beneficial to increasing the distillation speed, but the excess water and oil distilled out need to be cooled for better storage. The existing commonly used cooling method is to directly dissipate the heat, and the heat cannot be recovered and reused, resulting in energy waste.

[0004] Therefore, a vacuum distillation device for a paste reactor is needed to solve the above problems. Utility Model Content

In addition, the inner cylinder and the spiral tube are made of high thermal conductivity materials. By arranging the inner cylinder in the reactor and arranging the spiral conveying plate in the inner cylinder, the spiral conveying plate can be rotated to The paste at the bottom of the reactor is transported upward through the inner tube, and then the paste falls into the reactor from the top of the inner tube, which not only has a stirring effect on the paste, but also the hot water flowing from top to bottom through the spiral tube heats the paste, and the temperature gradually decreases from top to bottom. At this time, the lower temperature at the bottom will preheat the upward paste first, and then the higher temperature at the top will quickly heat the paste, thereby improving the reaction efficiency; by connecting the top end of the condenser tube to the water inlet of the heater on another reactor, and connecting the bottom end of the condenser tube to the cooler on another reactor, the reaction efficiency is improved. The outlet of the reactor is connected, and similarly, the top of the condenser on another reactor is connected to the water inlet of the heater on this reactor, and the bottom of the condenser on another reactor is connected to the water outlet of the cooler on this reactor. This arrangement enables multiple groups of reaction equipment to operate alternately, so that the recovered heat can be fully utilized. The cold water in the condenser exchanges heat with the steam in the steam pipe to become hot water, and then enters the heater for heating. Not only is the displaced hot air utilized, but the preheated water can be heated faster after entering the heater, thereby improving work efficiency, reducing heater energy consumption, and saving energy.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model arranges an inner cylinder in the reactor and arranges a spiral conveying plate in the inner cylinder. Through the rotation of the spiral conveying plate, the paste at the bottom of the reactor can be conveyed upward through the inner cylinder, and then the paste is dropped into the reactor from the top of the inner cylinder, which can not only stir the paste, but also the hot water flowing from top to bottom through the spiral tube heats the paste, and the temperature gradually decreases from top to bottom. At this time, the lower temperature at the bottom will preheat the upward paste first, and then the higher temperature at the top will quickly heat the paste, thereby improving the reaction efficiency.

The utility model connects the top end of the condenser tube with the water inlet of the heater on another reactor, and connects the bottom end of the condenser tube with the water outlet of the cooler on another reactor. Similarly, the top end of the condenser tube on another reactor is connected with the water inlet of the heater on this reactor, and the bottom end of the condenser tube on another reactor is connected with the water outlet of the cooler on this reactor. This arrangement enables multiple groups of reaction equipment to operate alternately, so that the recovered heat can be fully utilized. The cold water in the condenser tube is converted into hot water through heat exchange with the steam in the steam pipe to enter the heater for heating. Not only the displaced hot air is utilized, but the preheated water can be heated faster after entering the heater, thereby improving work efficiency, reducing the energy consumption of the heater, and saving energy.
